Maxim Integrated DS1642-100 Nonvolatile Timekeeping RAM

The DS1642-100 from Maxim Integrated is a state-of-the-art, nonvolatile timekeeping RAM that combines the function of a binary counter and a 64K x 8-bit static RAM. This innovative device is designed to provide a full-featured, battery-backed-up real-time clock (RTC) and memory storage solution in a single integrated package. Its primary application is in systems that require long-term, reliable timekeeping, even in the absence of a continuous power supply.

The DS1642-100 is characterized by its ability to maintain time and date information, from seconds to years, with the precision and accuracy expected from modern electronic systems. The timekeeping function is maintained for over a decade with the onboard lithium energy source. This ensures that timekeeping operations continue seamlessly even during power failures or when the main system power is turned off.

One of the key features of the DS1642-100 is its integrated crystal and lithium energy source, which are both encased within the module to prevent tampering and to provide a stable operating environment for the crystal. This design choice significantly enhances the reliability of the timekeeping functions and makes the DS1642-100 an excellent choice for critical applications where data integrity and timekeeping are paramount.

Additionally, the nonvolatile RAM aspect of the DS1642-100 provides 64K bytes of static RAM storage. The data stored in this memory is also protected by the onboard lithium battery, ensuring that critical data is not lost when the device is powered down. The static RAM can be accessed in the same manner as any other SRAM, making it easy to integrate into existing systems without the need for specialized interfacing or complicated software routines.

With its fully integrated package, the DS1642-100 offers a compact and reliable solution for systems that require nonvolatile memory and an RTC. Its wide operating temperature range and low power consumption make it ideal for portable and power-sensitive applications across various industries, including telecommunications, computing, and industrial control systems.

Overall, the Maxim Integrated DS1642-100 Nonvolatile Timekeeping RAM is a versatile and essential component for any system requiring robust timekeeping and data retention capabilities.
